ToFiniteField

converts the integer k to an element of the prime subfield of the finite field ff.

converts the coefficients of the rational expression expr to elements of the finite field ff.

converts the coefficients of the rational expression expr to elements of the finite field ff, with t representing the field generator.

Details

ToFiniteField replaces integers k with elements ff[{k}] of the prime subfield of ff and replaces t with the field generator ff[{0,1}].
ToFiniteField goes inside List, Plus, Times and integer Power in expr.
